Another problem is you have to convert your object oriented model (which RM is) to a relational model, which becomes complex in converting templates/aql to SQL. I have been that way. More then five years ago I left it. It is difficult doable, if you want a full featured openehr kernel. I would never recommend going this way, unless someone has a really smart idea.
It can work for a light featured openehr light derived application model.
